Abstract

1. Die Erfindung betrifft ein Belüftungssystem (1) mit einem Belüftungskanal (3), der im Wesentlichen von einem Rinnenunterteil (6) und einer gelochten Rinnenabdeckung (5) gebildet ist. Das Lochbild der Rinnenabdeckung (5) ist zur variablen Belüftung veränderlich. Die Rinnenabdeckung (5) ist dabei derart ausgebildet, dass ein vollständiger Lastabtrag in den Verlegegrund und/oder die Verlegeumgebung erfolgt, so dass die Dimensionierung des Rinnenunterteils (6) von der möglichen Belastungetwa beim Überfahren der Belüftungskanäle (3) mit Schwerlastfahrzeugen - weitgehend unabhängig von dieser möglich ist.
